Benchmarking re-entry prediction uncertainties (Parallel a)

The primary objective of the Benchmarking re-entry prediction uncertainties study is to fully exploit the informa- tion content of the GOCE observations and telemetry collected during its reentry phase for better understand- ing re-entry predictions in general and for GOCE in particular (ESA, 2015). Down to an altitude of 137 km, a rich data set of high-quality GPS, star tracker and also accelerometer observations were collected, be it that the latter were more and more saturated.
